MACHINE FOR MAKING PRINTING-SURFACES.`

SPECIFICATION forming part of Letters Patent No. 637,593, dated November 21, 1899. Application filed January 5, 1899. Serial No. 701,199. tllo model.)

To a/ZZ w/wnt it may concern.-

Be it known that I, EDWARD HETT, a citizen of the United States, and a resident of New York, (New Dorp,) Richmond county, State of New York, have invented certain new and useful Improvements in Machines for Making Printing-Surfaces, of which the following is a specification.

This invention relates to a 1n achine for making or preparing printing-surfaces upon printing-forms, whereby a design may be turned over, transferred, or otherwise imparted from a setting-up plate, transfer-plate, or other transfer-base upon or to a blank or unpre-l pared printin gfor1n-. e., a printing-form having a surface adapted to receive a design by transferand adapted to be thereafter developed and made suitable for printing.

The invention consists mainly of a curved or rounded stationary support and a support adapted to rotate and thereby traverse the stationary support, one of saidsupports being adapted to carry a printing-form and the other support being adapted to carry a transfer-base.

The invention also consists in the various features and combinations of features hereinafter set forth,and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification and in which like numerals designate corresponding parts in the several views, Figure 1 is a front elevation of the machine. Fig. 2 is a rear elevation. Fig. 3 is a side elevation looking in the direction of the arrow 1 in Fig. 1; and Fig. 4 is a sectional elevation on the line 4 4, Fig. 1. Fig. 5 is a longitudinal section of the printing-form audits suppport.

Referring now more particularly to the s pecific embodiment of the invention as illustrated in the drawings, 1 is a curved transthe printing-form 5 over or cause it to traverse the transfer-base. TheV printing-form when brought into contact with the design carried by the transfer-base rolls over the transfer-base, and thus receives the design to be imparted to it. In order that the rolling contact of the printing-form and the transfer-base may be positive, so that one may not slip over the other, a gear 11 is fixed on the shaft 7, carrying the printing-form, which meshes with the gear 12, fixed on the support 2. The boxes 13, which carry the shaft 7, are adapted to slide in recesses 14 on the ends of the arms 8. Carried by the arms 8 is a shaft l5, on which are fixed eccentrics 16, turning in straps 17, carried by the jointed arms 18, which are connected with the boxes 13, in which the shaft 7 is journaled. By operating the shaft 15 the cylinder 6, with the printing-form, may be forced down upon the transfer-base, so as to apply the pressure required in transferring or imparting the designs of the transfer-base to the printing-form. The shaft 15 is also employed to lift the cylinder 5, with the printing-form, out ofcontact with the transfer-base, so that gears 5 and l2 being disconnected the printing-form may be manipulated apart fromthe transfer-base. The recesses 14 in the arms 8 are formed by straps 19 and 20, pivoted to and forming a part of the arms 8 and connected at the top by the cross-pieces 21, pivifoted to the straps 19. When it is desired to remove the cylindrical printing-form from its, supporting cylinder, .the `cylinder 6 is lifted from the transfer-base and one ofthe arms 18 is disconnected from its box 13 and turned down out of the way. The corresponding end of the shaft 7 having been previously supported by suitable means-such as the apparatus shown in an application filed by Vme on `July l2, 1898, Serial No. 685,764- the cross-piece 21 is then turned back and the straps 19 and 20 turned down, when the printing-form may be slipped from its cylinder 6. If desired, however, the shaft 7 and cylinder 6, with its printing-form, may be all removed together.

The printing-form may be removed from the machine and the printing-surface thereof developed apart, if desired; but the'printingsurface is preferably developed before the IOO form is removed from the machine, andkforthis purpose Iprovide the machine withfthey inking and dampening frames 22 and 23, car` distributing cylinder 25, WhichcarriesgearL` 26, arranged to drive the in-king-rollers. The inking-fraine is moved to and from the printingform by means of the hand-shaft 25, on

. which is fixed the gear 26, meshing with the the' dampening-frame.

anism' ofl'th'e machine is so arranged that the 1'5 be'arranged to be positively driven like the K hiring-rollers. I Will nowvdescribe the driv-' gear 27 v-on fthe- Worm-shaft 28, WhichV carries.

-32 is fthe pulley-shaft, on Which isxed a beveledgear 33, meshing with the beveledi The clutch-37 serves'to lock either the gearl 34 or' gears34 and 35, loose on the shaft 36.

th'ewgear 35 on the shaft 36, as occasion requires. The clutch' is operated by the-lever `38,@p'rovided with `the gear 39,I meshing Withv theiworm-shaft 40. Loose on the shaft 36arev two gears 41 and 42, arranged to be locked on the-shaft bythe clutches 43 and 44, respectively. These clutches are operated -by the Y- shaped lever 45, provided with` the' gear 46, meshing with the Worm-shaft 47. They gear42 meshes With the gear 52,11oose on 4the shaftf53, and the gear 43 meshes with the gear The gear 52 meshes' with' theI gear 10, and when the clutch 44 is operated to lock the gear 42 fast on its shaft 54-,loose-on the shaft 53.

andthe pulley-shaft 32 is operated the arms 8 are-actuated to carry the printing-form over the-transfer-base, the movement of thearms being yreversedby a reversal of the shaft 36.

The gearl 54 meshes with the lgear 48, fixed The gear 48 is also mesh'ed' WiththegearO, loosely mounted on the shaft- 51, upon which the dampening-frame23 is` fixed. The gear 50 also`meshes With th'e'gear 26 on-the main?A ink-distributing cylinder.

When-it-is desiredlto roll up the printingsurface in developing it, the gear 41 is made The dampening-framev 23 isV` moved to Vand from the printing-form by means of the hand-shaft 30,on which are fixed The driving mech-y the. driving mechanism may be eect'ed Without departing from my invention. A It Will also be evident that various changes in the ,form and arrangement of various parts may be made Without departing from my invention.A For example, instead of having the printing-form `reciprocate and roll over the transfer-base l may arrange the transfer-base so as to reciprocate and rotate over theprinting-form.` This could be effected by mounting a transfer-base of suitable size upon the cylinder-v6 and .mounting a printing-form of suitable size upon the support 2. The printing-surfaceiof the form may be developed so ras to be planographic, relief,'or intaglio, and in the yprocess of development employedthe printing-surface may be lightly` orl deeply etchedfandwrouted out, orl it maybe developed in` any other suitable Way. In-.thepreferred embodiment of the invention the trans-` fer-base is in the form of a setting-up plate,

lon which theordinary transfers will bestruck up, so that the transfers may be turned over upon the printing-form, inV accordance withthe practice of transferring in the lithographie upon itsisupport in a predetermined Aposition i both longitudinally and transversely. The means shown inV thedrawings for attaining the transverse or circumferential position consists of internal 'ribs 7 O on the printing-form, adapted to slide in corresponding groovesin thesupport-in-g-cylinder-a marked rib in a marked groove. For attaining the longitudinal position of the printed form on its supportany suitable means may be used. The means preferably employed consist of a'stop or shoulder 71 on the end of the support, as shown 'inV Fig.' 5, against which the prin-tingform is located, all `as more fully set-forth in application filed by me the 7th of February, 1895, Serial No. 537,582. Thus it Will be seen that an accurate prestablished seat is-A provided for the printing-formand successive` printing-forms. The successive printingforms designed to be'manipulated in the machine are provided VWith similar means, so-as to insure that these successive printing-forms shall be mounted inthe same relativesituationon the supporting-cylinder 6. The transfer-baseorsetting-up plate is also provided with devices, so as to insure that it shall always be mounted in the same relative posi-` tion on its support. As shown inthe drawings, the transfer-base is provided Withears 55,1itting in: corresponding recesses-in the support 2. The locks 3 engage the ears*- 55 and hold-'fthe setting-up plate rmly in place.v Thus itwill 'be seen the. transfer-base :is pro= vided Withan accurate prestablished lseat, whereby it may be arranged in exact prede- IOO IIO

termined position both longitudinally and transversely. Intermeshing gearing for the transfer-base and printing-form are so marked as to insure that they shall always intermesh in the same way. By means of these prestablished guides it will be seen that a printing-form and its coacting setting-up plate or transfer-base may always be brought into contact in an accurate predetermined relation both longitudinally and transversely, so that duplicate identical and interchangeable printing-forms may be readily made and accuracy of register may be obtained in the operation of preparing the printing-surfaces thereof.
